3. TO REPLACE THE BATTERIES
1) Loosen the screw on the back of the SF-4300A /
SF-4600 that holds the battery compartment
cover in place, and remove the cover.
2) Loosen the screw that secures one of the three
battery holders in place and remove the battery
holder.
Caution
Be sure to remove only one battery at a time.
Otherwise, you will lose all data stored in memory.
3) Replace the old battery with a new one, making
sure that the positive (+) side of the new battery
is facing up (so you can see it).
4) Replace the battery holder and secure it by tightening its screw.
• Be sure careful that you do not over tighten the screw.
5) Repeat steps 2) through 4) for the other two batteries.
• Be sure to replace all three batteries. Never mix old batteries with new ones, and be sure
to use CR2032 lithium batteries only.
6) After you replace all three batteries, replace the battery compartment cover and secure it
by tightening its screw.
• Be careful that you do not over tighten the screw.
